Simplify the expressions....
(3x^4+12x^3-2x^2)+ (5x^4-x^3+7x^2)
First: eliminate parenthesis - rewrite the expression excluding parenthesis.
3x^4+12x^3-2x^2+5x^4-x^3+7x^2
Sec: combine "like" terms - combine coefficients with the same variable & degree.
3x^4+5x^4+12x^3-x^3-2x^2+7x^2
= 8x^4 + 11x^3 + 5x^2

Go with "II". Addition is really easy; add terms with like powers. For example, the 4th power terms are 3x^4 and 5 x^4; their sum, 8x^4.

i actually wish teenagers might give up posting retardedly simplistic homework that would no longer be defined without basically providing you with the solutions. Ask your mothers and dads that can assist you. in the event that they are actually not in a position to determine those out then.... my god...

what does it equal? the equation is not complete.
once it is, set it equal to 0 and use the quadratic formula to solve (factor)
the quadractic formula:
